About 57 O
Reverse dateless plates place the numbers before the original local index letters, so the registration carries local authority provenance without a year marker. The O index mark traces back to Birmingham, now associated with West Midlands. This reverse sequence was issued from the 1950s onwards as earlier dateless runs became exhausted. At 3 characters, 57 O sits in a very short collector tier.
